PRESSING DEVICE.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Applioatlen'flled August 20, 1915. Serial No. 46,520.

To all whom it may concern:

Be it known that 1, WILLIAM F. LAU rnN- SCIILAGER, a citizen of the United States residing at Cincinnati, in the county of amilton and State of Ohio, have invented certain new and useful Improvements in Pressing Devices, of which the following is a specification.

My invention relates to a ressing device applicable for pressing fiexi le material in machines such as folding machines for folding the edges of shoe uppers-01 other flexible material used for instance in gloves, pocket books, and other articles; in beading machines for pressing or heading for instance the heads at the sides of the seam of a. shoe up er; in shoe-upper blocking machines, an other machines employing a presser acting on the flexible material..

have excm lified m invention as employed in a fol ing mac ine such as shown, described and claimed in my ap lication for Letters Patent of the United tates on improvements in folding machines Serial No. 634,485, filed June 21, 1911. I have in the drawings exemplified the pressing device as employed for pressing thevmargin of flexible matemal bein folde such as a shoe upper, and have in icated the feeding, snipping and folding means of such amachine.

' These means as well as the pressing device may be operated in manner similar to that shown, described and claimed in my aforesaid application.

My mvention will be further readily understood from the following description and claims, and from the drawings, in wh1ch latter:

Figure 1 is an end elevation of so much of the folding machine as is necessary to illustrate my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a plan view of the same.

Fig. 4 is a rear end elevation of the operating means for the presser.

Fig. 5 is a central cross-section on the line 5-5 of Fig. 3, shown in connection with a piece of flexible material, with the fold portion of the margin of the material about to be laid u on the body portion of the margin, and in tlie relation in which the prcsser is about to exert pressing action upon the fold being laid.

Fig. 6 is a similar view, showing the anvil 27 of the material-support.

presser in pressing relation, with the bod) of the presser shifted with relation to its pivot for exerting its pressing function.

F i 7 is a vertical axial section on the line l of Fi 2; and,

Fig. 8 is a diagrammatic representation showing the changesin relation of the par-ts during operation in the present exemplifies tion.

11 re resents a material-sup ort, which may be orizontal as shown, or p ac'ed at any desired angle with relatlon to the horizontal, or in vertical position, as may be desired.

12 represents a feeding-foot, operated in manner heretofore mentioned, designed to Cooperate with a feeding roller 13, to impart step-by-step or progressive feedin movements to the piece of flexible materia exemplified at 14. A snipping knife 15 may if desired be employed and 13 arranged to co-act with a snippm block 16, and is designed to snip or cut t e fold-portion of the margin to be folded, crosswise of the fold, when desired, during the feeding movements. A folding block 19 has a. plow-shaped foldin face and is arran ed-to partially turn 1; e foldortion 21 o the mar '11 of the material, or instance along a f d 22, the position of which is determined in suitable manner, and is instanced as determined by the folding block in connection with the foldresser.

25 represents the presser instanced as a fold-Presser, and is arran ed to normally oscillate about a pivot 26. his pivotal axis of the pivot is shown in substantially the plane of the, material-supportin face or %he pressing-face 28 of the presser is arranged to co act with the material-support 11, in close proximity to the ivot position of the Presser so as to re uce the throw of the pressing portion of the presser as much as possible.

When the presser hasbeen swung toward the materialsupport in such relauon as to begin the pressing function upon the material, the pressing face of the presser is preferably distanced from the material-supporting face of the material-support at its point of closest approach to the material, a distance equal to the thickness of the folded margin of the material employed, this distance being adjustable by the adjustment of the body of the presser hereinafter described.

The pivot of the presser is exemphficd as a shaft, nhich may be a stationary shaft, fixed in bearings 30 of the main frame 31 of the machine. A bushing, 32 is received about the shaft, the bushing rocking about the shaft with the body of the prcsser. This bushing is in a slot 33 in the presser, the presscr being movable lengthwise of this slot and crosswise oftthe bushing and pivot shaft 26. D

There is a socket 34 in the press-er, m which a spring 35 is located. 36 is an adjusting screw adjustable in the threaded end 37 of the socket and-is arranged to adjust the tension of the spring 35. This spring adjusts the pressure applied by the presscr. D e

For adjusting the normal position of the body of the presser and the distance of its pressing face from the material-supporting face of the material-support when in pressing relation, I provide a set-screw 38 in a threaded hole 39 of the presser, arranged to eonta'ct the bushingfor adjusting the distance between the upper end of the slot. and the bushing and positioning the pressing face ofthe presscr withrelation to the supporting face of the material or anvil, for aceommodating difl'erent thicknesses of mate- -rial.5" The sct-sereW is locked in place by means of a lock-screw 40, screwed in the threaded hole 39' upon thesct-screw .38.

For opt-rating the presser I have instanced ash" ft 44', -which has alcrank-pin 45- thereon, 'l'aich is articulated with the tail 46 of the rcsser by means of links 47, 48. and 49. The t link 47 has a bearing about the crank-pin 45. A pivot-pin 53 connects the links-.f47, 48, by being located in bearings 54 of tlielink 47 and a bearing 55 of .the linlc 48'. The links '48 and 49 are connected by a pivot-pin 57 located in bearings of the link 48 and in a bearing 59 of the link 49. The link 49 hasu bearing 60 arranged with in fork-like bearings 61 in the tailAG, an articulating pin 62 being located in aid bearings. a

If desired, the spring may extend into a'socket 6% in the adjusting scrmv ltl, and be heldjat its lower end against an annular shoulder id-therein.

vI-have in Fig. ft diagi'ainmatically illustrated the preferred-relation of the prcsser toithc material-support, -.when the pressing face 28 of the presser has been moved hv the operating means toward the materiab supporting face, and in theabscnceiof ma terial between the pressing face and the material-supporting face. In such relation the presser-face 28 is preferably distanced, as by'the space 68, from the material-support ing face 27 of the material-support 11, but

pundit-l therewith. This space represents for instance the thickness of the pressed folded portion of the material.

The pivotal axis 26 of the presscr in in the plane of the llliltl'lltlln llIPPUIUIIQ; surface, represented by the tlnllt'tl line if), the articulatim. axis 62 of the operating means being preferably also in this plane, when at its uppermost limit of moven'ient.

In operation, the fold-portion of the margin bein; folded is partially folded by the folding-block 19. The partially folded foldportion is laid toward the l'mrly-portiou of the margin along the fold by a rocking movement of the preswr about its pivotal axis '20, with the boil) of the prt-sser in normal relation with the pivotal axis, as illustrated in Fig. 5, the articulating axis 62 being now below the plane of the material "support.

A further movement of the axis of articulation 62, instanced as an upward movement, will camunpressure to be exerted upon the fold being pressed, causing yield of the body of the press-er at its pivotal axis 26, (see Fig. 6), for pressing the fold-portion upon the body of the margin with a movement of the fold-pressing face-of the presser direct; to ward said body, whereby lateral shifting of the fold-portion andfold is prevented, and the fold caused' to'bc lnid in a true line.

In order to insure such movement I arrang: the 'slot 1-33 on an are, illustrated by the dotted linefIO in Fig. 8, described from the point-71 in the pmssing-face -28 as a center, this center-point representi the point of contact'of the pressing-face wi the fold 22. This has the further advantage in that it insures pressure upon said fold; and enablesa thin fold-edge, much desired in shoe-making practice, to be obtained.

In the pressing movement. the pres-set practically swings upon the fold-portion of the margin from the point 71 as a pivot, the slot 33 lat-int descri ed on an are from Said point as a center for preventing lateral shifting of the presscr-face 28, the articulating axis 62 of said presscr with itsoperating means rising to the position indicated in Fig. when said fold portion is pressed.
